Initial analysis

The 100-unit multi-family residential building at 531-621 Arballo Drive in Stonestown, owned by Parkmerced Owners LLC and built in 1942, has experienced several significant maintenance and safety issues in recent years. Most notably, there are current and recent concerns about moisture problems, including active complaints from 2024 regarding window/ceiling leaks and bathroom mold. The building has a documented history of electrical and plumbing upgrades, including multiple roof replacements between 2007-2010, gas line replacements in 2016-2017, and electrical system upgrades in 2007-2008. A cluster of building violations from late 2018 related to mold, lead paint hazards, and smoke detector issues was officially abated in December 2018.

The property has experienced recurring water-related issues, with multiple building complaints about leaks and mold documented between 2018-2024. There were also concerns about illegal occupancy and associated storage problems in 2022. In terms of fire safety, the building has had several smoke detector activations and false alarm incidents, as well as a few minor rubbish fires in and around the building between 2010-2015, though none resulted in civilian injuries. The building's maintenance history shows regular upkeep of major systems, including multiple reroofing projects and electrical system improvements, though the recurring nature of water-related complaints suggests ongoing challenges with moisture management. Recent permits and violations have been properly addressed according to city records, with no active building violations at the current time, though the recent moisture issues may indicate continuing concerns in this area.

Risk rating

How 531-621 Arballo Dr's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile

Out of 31 buildings in this neighborhood, 31 are predicted to be safer.
